Bottom Line:
Results of the Pearson chi-squared test (χ2) showed a positive association between CDC-LT and species of Culicini and Uranotaeniini tribes.Additionally, our results suggested a positive association between CDC-A and representatives of the Culicini and Aedini tribes, whereas the MMI was positively associated with the Mansoniini and Sabethini as well as with Anophelinae species.Results of the present study showed that MMI performed better than CDC-LT or CDC-A in sampling mosquitoes in large numbers, medically important species and assessing diversity parameters in rural southeastern Atlantic Forest.

ABSTRACTTraps are widely employed for sampling and monitoring mosquito populations for surveillance, ecological and fauna studies. Considering the importance of assessing other technologies for sampling mosquitoes, we addressed the effectiveness of Mosquito Magnet® Independence (MMI) in comparison with those of the CDC trap with CO2 and Lurex3® (CDC-A) and the CDC light trap (CDC-LT). Field collections were performed in a rural area within the Atlantic Forest biome, southeastern state of São Paulo, Brazil. The MMI sampled 53.84% of the total number of mosquitoes, the CDC-A (26.43%) and CDC-LT (19.73%). Results of the Pearson chi-squared test (χ2) showed a positive association between CDC-LT and species of Culicini and Uranotaeniini tribes. Additionally, our results suggested a positive association between CDC-A and representatives of the Culicini and Aedini tribes, whereas the MMI was positively associated with the Mansoniini and Sabethini as well as with Anophelinae species. The MMI sampled a greater proportion (78.27%) of individuals of Anopheles than either the CDC-LT (0.82%) or the CDC-A traps (20.91%). Results of the present study showed that MMI performed better than CDC-LT or CDC-A in sampling mosquitoes in large numbers, medically important species and assessing diversity parameters in rural southeastern Atlantic Forest.

The results of the χ2 test showed the presence of a positive associationbetween the CDC-LT and species of the Culicini and Uranotaeniini tribes. Thespecies/taxonomic units belonging to the Culicini tribe represented 77.23% of the totalabundance sampled by the trap (χ2 = 4594.040; p < 0.000). As compared withthe other traps, the CDC-LT was highly selective for species of the Ura- notaeniinitribe, capturing 126 individuals, representing 99.21% of the total species of the genusUranotaenia collected by the traps. Only one individual was capturedby MMI. Regarding the CDC-A, there was a positive association between the trap andrepresentatives of the Culicini and Aedini tribes. Thus 62.72% of the mosquitoescaptured in the trap belonged to the Culicini (2,972 insects), whereas 4.91% were of theAedini (233 individuals). The MMI showed a positive association with species of theMansoniini and Sabethini tribes and the Anophelinae subfamily. Mosquitoes of theMansoniini represented 65.51% (6,510 individuals) of the specimens obtained in the MMI,252 mosquitoes were of the Sabethini and 479 belonged to the Anophelinae subfamily. TheMMI was capable of capturing a greater number of Anopheles than theCDC-LT and the CDC-A (Table II), about 78% ofAnopheles collected. The results of the correspondence analysis aregiven in Fig. 2, which shows the associations ofthe traps with the subfamilies and tribes.
